Following upgrade to Mac OS X 10.9 Mavericks, Outlook 2011 (fully updated) started reporting frequent errors with mail connections. ALL my five email POP account servers report error with time-outs, dropped server connections, cannot find mail server, etc.  One of my IMAP servers also started reporting Idle errors. I get a dozen of these an hour. When ignored, mail is still being sent and received. Some Apple Community posters recommend migrating to a new user, but I am not sure that will solve the problem. Is Microsoft aware of this problem (reported by dozens on the Apple boards) and are they working on a fix?
